DESCRIPTION AND CONDITIONS: Florence Acres is a 13 lot, 9 acre subdivision. The subdivi- sion is located on the north side of 4th Street west of 38th Avenue. The subject property is zoned R-1 (6.2 dwelling units/acre) and has a LD -2 land use designation (6 dwelling units/acre). The subdivision's proposed density is 1.4 dwell- ing units/acre. Florence Acres received preliminary plat approval from the Board of County Commissioners on May 5, 1982. According to Section A(3)(g) of the County's Subdivision Ordinance 75-3. "(g) The following limitations and conditions are placed on the preliminary plat approvals given by the Board: (1) The approval of the Board shall have full force and effect for a period of -18 months from the date of approval. An extension may be granted by the Board. (2) If no final plat has been filed for the area covered by the preliminary plat before the approval period has elapsed, the approval shall be revoked. If final plats are filed for only a portion of the preliminary plat, the approval on the remaining portions shall be revoked unless, an extension of time has been granted by the Board." Thus, according to. the subdivision ordinance which was in effect at the time that this plat was approved, the preliminary plat of Florence Acres expired on November 5, 1983. The applicant is requesting that the Board of County Commis- sioners grant a variance from this provision of the subdivision ordinance, thus, in effect, granting an after -the -fact exten- sion of preliminary plat approval. ALTERNATIVES AND ANALYSIS: In evaluating this request, staff took two factors into consid- eration. First, staff considered what new County Ordinances have been adopted since the preliminary plat of Florence Acnes was approved, enforcement of which would benefit the County. SecW103.v- Staff considered the progress which the applicant has mare iTi %oinp] eti ng the subdivision's improvements. Si nr7p +-hn subject plat was approved, the County has adopted its Compre- hensive Plan, as well as new subdivision, stormwater management and flood protection and tree protection ordinances. The plat conforms to the standards in the County's newly adopted land development regulations, with one exception. The. County's Thoroughfare Plan categorizes 4th Street as a primary collector street. The required right-of-way width for a primary collector street is 100'. The plat of Florence Acres shows an existing 60' right-of-way, with an additional 10' being dedicated at the time of final plat approval. Thus, there is 70' of right-of-way, where 100' is needed. Staff recommends that the applicant reserve An additional 30' of right-of-way along the length of the development's 4th Street frontage. This can be done without changing the size or configuration of the lots in the subdivision. The only lot which would be affected is Lot 1. The approved preliminary plat shows a 50 foot building setback line along this lot's 4th Street frontage. A 20 foot front yard setback is required in -the R-1 zone. Thus, the applicant can change the 50 foot building setback line to a 30 foot road right-of-way reserva- tion and still have a 20 foot building setback as required by the ordinance.
